ASO implantation is less invasive than the surgical procedure with low morbidity and mortality rates and is thus widely indicated in the treatment of the ASD [1, 2]. However, a major complication with ASO is aortic erosion, which can lead to lethal bleeding. The incidence of this dangerous complication has been reported to be range from 0.1 to 0.3% [1,2,3], which is not very frequent. However, the mortality rate was reported to be as high as roughly 20% [3].

Regarding the mechanism underlying aortic erosion, Amin et al. strongly speculated the absence of the aortic rim of the defect as being involved. They reported that 25 of 28 patients (89%) with erosion had an aortic rim of < 5 mm [4]. A device that oversized and straddled the aortic root was thus believed to carry a risk of causing erosion. When a patient has a deficient aortic rim, the device tends to be placed by straddling it over the...
